Executive producer, writer and showrunner Veena Sud will return, as will lead actors Mireille Enos and Joel Kinnaman. The new season will center on a new case, which — unlike the Rosie riddle — will resolve over the course of 12 episodes.

The show will pick up a year after closing the Larsen case. Linden won’t be a detective anymore, but when Holder discovers a string of horrific murders that connects with one of her old investigations, she’ll be drawn back into action.

Billy Campbell’s Mayor Richmond won’t be part of the third season; neither will Brent Sexton or Michelle Forbes, who played Rosie’s parents. New characters include Tom Seward, a death-row murderer reminiscing about his bloody past; Ed Skinner, Linden’s old partner who might have shared an extramarital moment with the redhead; and Dannette Lutz, a terrible mother whose 15-year-old daughter goes missing.
